That's the idea.

So you want to test for test1 OR test2 on each line, not test1 AND
test2?

You could run ps into a file, then loop over each test:

  tmpfile=/tmp/pstest$$
  ps ... >"$tmpfile"
  ok=1
  for test in test1 test2 test3 ...
  do  egrep "$test" "$tmpfile" >/dev/null || { ok=; break; }
  done
  rm "$tmpfile"
  [ $ok ]
